We have recently engaged a well known, international company to carry out integrity (sonic echo) testing of bored end-bearing piles installed on one of our contracts.
As there were no significant impedence changes shown in the results of the tests on the P.I.T. machine, we were reasonably confident that the installed piles were acceptable. However, further to analysis of the results, we have received only a very small (1 page) report from this company stating that "All piles have been succesfully tested and no significant defects have been found".
Does this lack of information strike anyone else as odd? Whilst I have absolutely no reason to doubt the integrity of the statement in the report, on previous contracts we have been provided with a full report, showing graphs for each pile tested using this method.

The report is incomplete,it should attach a graph for every test pile showing the velovity,pile length etc,from which we can say that the piles' integrity is good.

"significant" defects... My "significant" isn't the same as another persons "significant".
I agree with Henry that the full report be included so that we (the engineers) can decide on the significance of the defects ourselves. To accept this report is to take on the risk for incorrect interpretation of results ourselves. We may delegat but we remain wholly responsible.
Just a joke: $50000 for Bill Gates is "insignificant" but in Malaysia, I'll consider selling my relatives for this money!

Usually we use the sonic echo test as a confirmatory test. It is preferable to use the frequency response test and only if data is diificult to interpret do we carry out a sonic echo test. Just a thought though.
